Article 2.208 (ex art. 5.209) - Modified Acceptance

(2) A reply which gives a definite assent to an offer operates as an acceptance even if it states or implies additional or different terms, provided these do not materially alter the terms of the offer. The additional or different terms then become part of the contract.
